Load balancing in telecommunications system supporting mobile IP
First Claim
Patent Images
1. A method for balancing load in a telecommunications system supporting Mobile IP, the system including at least one primary home agent configured to support mobility of at least one mobile node and capable of intercepting and tunneling packets, the method comprising:
- adding one or more secondary home agents to the telecommunications system, in addition to the at least one primary home agent;
processing, in the primary home agent, registration requests, sent from the at least one mobile node or a foreign agent serving the mobile node in a visited network;
transmitting packets destined for the at least one mobile node via the primary home agent in response to receiving an acceptable registration request from the at least one mobile node or the foreign agent;
sending a routing request to the one or more secondary home agents to transmit packets destined for the at least one mobile node;
intercepting and tunneling packets destined for the at least one mobile node by the one or more secondary home agents in response to the routing request; and
stopping packet transmission to the at least one mobile node via the primary home agent.

Abstract
A method for load balancing in a telecommunications system supporting Mobile IP, the system including at least one mobile node and at least one home agent. The home agent mainly supporting the mobility of the mobile node is defined as the primary home agent and one or more secondary home agents are added to the telecommunications system. Packets destined for the mobile node are transmitted, when needed, via one or more secondary home agents.
